Title: **Innovative Contributions of Charles H. Crockett, Jr.**
Introduction
Charles H. Crockett, Jr. is an accomplished inventor based in Austin, TX, with a notable career in the field of engineering and technology. He holds five patents that showcase his innovative prowess, particularly in the area of circuit board manufacturing.
Latest Patents
His most recent patents include advanced methods for manufacturing multiple layer circuit board die carriers. One of the critical innovations he developed involves the method of creating stacked vias of fine dimension and pitch. The process starts with a base laminate featuring a conductive pattern coated with a dielectric. This dielectric undergoes photolithographic processing to create holes that expose selected areas of the conductive pattern underneath.
These holes are then plated to establish via connections between the surface and the conductive pattern on the base laminate. The recess generated by these vias is filled with a conductive and plateable polymer which, upon curing, forms a conductive plug. A second dielectric layer is added and similarly processed to reveal the underlying plated via and plug, allowing for the creation of a second via that is vertically aligned and electrically connected to the first. This technique of fine pitch stacked vias is essential for printed circuit board structures, especially in applications like flip chip die carriers, ensuring minimal area usage and reduced electrical degradation.
